Heterogeneity in Intra-Monthly Consumption Patterns, Self-Control, and Savings at Retirement
利用美国个人食物摄入调查数据，发现退休储蓄不同的群体在月度内消费模式存在差异：有储蓄者消费平滑，无储蓄者在领社保前一周比后一周少摄入25%热量，这符合双曲贴现理论。
Using data from the Continuing Survey of Food Intake by Individuals, this paper describes the shape of consumption profiles over the month for Social Security benefit recipients that have saved different amounts for retirement. Individuals with income mostly made up of Social Security and savings smooth consumption over the pay period, while individuals without savings consume 25 percent fewer calories the week before they receive checks relative to the week afterwards. The findings for individuals without savings, who comprise about a fourth of our sample, are inconsistent with the standard Life Cycle-Permanent Income Hypothesis but are consistent with hyperbolic discounting.
